An assessment of the use of patient reported outcome measurements (PROMs) in cancers of the pelvic abdominal cavity: identifying oncologic benefit and an evidence-practice gap in routine clinical practice.

BACKGROUND: Patient reported outcome measurements (PROMs) are emerging as an important component of patient management in the cancer setting, providing broad perspectives on patients' quality of life and experience. The use of PROMs is, however, generally limited to the context of randomised control trials, as healthcare services are challenged to sustain high quality of care whilst facing increasing demand and financial shortfalls. We performed a systematic review of the literature to identify any oncological benefit of using PROMs and investigate the wider impact on patient experience, in cancers of the pelvic abdominal cavity specifically. METHODS: A systematic review of the literature was conducted using MEDLINE (Pubmed) and Ovid Gateway (Embase and Ovid) until April 2020. Studies investigating the oncological outcomes of PROMs were deemed suitable for inclusion. RESULTS: A total of 21 studies were included from 2167 screened articles. Various domains of quality of life (QoL) were identified as potential prognosticators for oncologic outcomes in cancers of the pelvic abdominal cavity, independent of other clinicopathological features of disease: 3 studies identified global QoL as a prognostic factor, 6 studies identified physical and role functioning, and 2 studies highlighted fatigue. In addition to improved outcomes, a number of included studies also reported that the use of PROMs enhanced both patient-clinician communication and patient satisfaction with care in the clinical setting. CONCLUSIONS: This review highlights the necessity of routine collection of PROMs within the pelvic abdominal cancer setting to improve patient quality of life and outcomes.

[Quality assessment of radiologic reports of CT examinations for tumor response evaluation]. / Évaluation de la qualité des comptes rendus radiologiques des examens tomodensitométriques d'évaluation oncologique.

PURPOSE: Our purpose was to assess the quality of radiologic reports of CT scans performed for tumor response evaluation before and after corrective procedure. MATERIALS AND METHODS: Our objective was to assess the presence of different items in radiologic reports of CT scans performed for tumor response evaluation. The present evaluation was formal, that is to say without checking the accuracy of the items identified. Ten simple items were evaluated before and after corrective procedure corresponding to an oral and written information concerning the tumor response evaluation technique with CT. RESULTS: The results were variable depending on the items measured. Most of the criteria were improved after corrective procedure. But for some items the result remained poor or very poor as the appropriate choice of comparison review (baseline or nadir). CONCLUSION: In the absence of use of the standard form, the feedback of the quality of radiologic reports of CT scans performed for tumor response evaluation shows that the quality remains largely suboptimal even after corrective procedure.

Fetal intra-abdominal tumors: assessment of spectrum, accuracy of prenatal diagnosis, perinatal outcome and therapy at a tertiary referral center.

OBJECTIVE: To describe the varieties and ultrasound characteristics of prenatally diagnosed fetal abdominal tumors and to scrutinize the accuracy of prenatal diagnosis as well as the postnatal outcome and therapy of affected pregnancies. STUDY DESIGN: Retrospective study of 354 fetuses found to have abdominal tumors on prenatal sonogram, identified from 1993 to 2009 at a tertiary referral center for prenatal medicine. The cohort was classified into subgroups according to the sonographic appearance of the fetal tumor and the affected anatomic structure (urinary, gastrointestinal and genital tracts and other locations). Sensitivity, specificity, positive predictive value and false-positive rate of ultrasonography in identifying the system of origin were calculated. Relationships between relevant outcome domains and the different subgroups were assessed using the chi-square test and Fisher's exact test. RESULTS: Our cohort comprised 222 urinary tract lesions, 37 genital tract lesions, 80 gastrointestinal lesions and 15 tumors of other origins. The mean gestational age at diagnosis was 26+0 wks. The prenatally established diagnosis was exactly concordant with postnatal findings in 88.9%. Sensitivity, specificity, positive predictive value and false-positive rate of ultrasonography in identifying the system of origin (urinary, gastrointestinal, genital tracts and other locations) were 98.3%, 97.6%, 92.6% and 2.4%, respectively. The favorable postnatal outcome rate was highest among fetuses with genital tract lesions (95%) and lowest among those with tumors of the urinary tract (62%, p=<0.001). Twenty per cent of tumors regressed spontaneously, mostly gastrointestinal tumors (36%, p=<0.001). In 75/354 cases (21%) the parents opted to terminate the pregnancy: intra-uterine fetal demise and neonatal death were each noted in 4%. Prenatal therapy was performed in 24 of 354 cases (7%) and postnatal surgery in 64 cases (18%). CONCLUSION: The majority of fetal abdominal anomalies were accurately diagnosed and the vast majority of affected fetuses had a favorable outcome, some tumors even resolved with advancing pregnancy. Pre- and post-natal invasive surgical interventions were mandatory in only a small number of cases.

Resting energy expenditure in children newly diagnosed with stage IV neuroblastoma.

Children with stage IV neuroblastoma (NBIV) are often malnourished at time of diagnosis, observed as high as 50%. The emphasis of this study was to determine whether an increased resting energy expenditure (REE) is a causative factor. Our hypothesis was that children diagnosed with NBIV have an increased REE, which normalizes with cancer treatment. Changes in nutritional status from time of diagnosis in response to nutritional support were examined. REE and nutritional evaluation were obtained three times: at diagnosis before starting treatment, where tumor burden is expected to be highest; after two courses of chemotherapy, where some response to treatment is expected; and after surgical excision of the primary tumor, where there was presumably minimal residual disease. Ten subjects completed the study. Results showed that REE was not increased, and there was no significant difference between phases (p = 0.29). Fifty percent of our subjects were malnourished at diagnosis. Because REE is not increased in NBIV, it is concluded that malnutrition seen in NBIV is not due to increased energy needs, but is likely due to decreased intake because of the intra-abdominal mass and malignant malaise.

[Value of diagnostic imaging for assessment of unsuccessful treatment of children with neoplastic diseases. Introductory comments based on personal examinations]. / Wartosc badan obrazowych dla diagnostyki niepowodzen leczenia dzieci z choroba nowotworowa. Doniesienie wstepne na podstawie wlasnych badan.

Diagnostic imaging has determined clinical application depending on kind of pathology and anatomical localisation. This is a precise and fine instrument for monitoring effects of treatment in childhood malignant tumours. Authors demonstrate examples of cases in which diagnostic imaging was the only method which revealed a relapse in situ, progression during chemotherapy or clinically unsuspected dissemination of tumours after many years.

Intraoperative radiation therapy and hyperthermia. Morbidity and mortality from this combined treatment modality for unresectable intra-abdominal carcinomas.

This is a report of a phase I trial of intraoperative radiation therapy in combination with intraoperative hyperthermia for the treatment of locally advanced, unresectable intra-abdominal carcinomas. Using an ultrasound transducer system specifically designed for intraoperative applications, 19 patients have been successfully treated, demonstrating the feasibility of this combination modality. The morbidity (58%) and mortality (11%) rates reported in this series are comparable to rates reported in series of similar patients receiving intraoperative radiation therapy alone. There is still a great need for considerable technological development to enable the use of intraoperative hyperthermia to treat large, complexly shaped intra-abdominal tumors, and phase II and III trials of this combination treatment modality should be performed.

Home parenteral nutrition for patients with advanced intraperitoneal cancers and gastrointestinal dysfunction.

The use of total parenteral nutrition (TPN) in patients with advanced, untreatable cancer is controversial. Occasionally, however, damage to bowel by tumor, radiation, or surgery renders these patients unable to eat and TPN may be indicated to prevent premature death from starvation. We have used Home Parenteral Nutrition (HPN) to support three patients with advanced, untreatable abdominal cancer and inability to eat. Morbidity was minimal and survival times were 24, 6 and 1.5 months. Payment was covered by third party agencies. All patients and their families were gratified by the ability to return home with nutritional support. HPN can be used to support terminal cancer patients with bowel obstruction and may afford them longer survival. Ideally, patients considered for this should be well motivated, with good support systems, and with survival estimated to be at least months.

Abdominal computed tomography in small cell lung cancer: assessment of extent of disease and response to therapy.

Abdominal computed tomography (CT) was performed as part of the initial staging evaluation in 77 patients with small cell carcinoma (SCC) of the lung. CT scans revealed mass lesions in 26 patients (34%). Abnormalities were confined to the liver in 15 patients and to retroperitoneal structures (lymph nodes, adrenal glands, psoas muscle region masses) in eight, and occurred in both areas in three. However, only three of 29 patients otherwise staged as having limited disease (confined to one hemithorax and regional nodes) had evidence of abdominal metastases on CT scan. Most (23/26) positive studies were in patients already known to have more extensive tumor dissemination. In 71 patients with pathologic confirmation of liver status, CT had a sensitivity of 63%, specificity of 91%, and overall accuracy of 85% in assessing the liver. Comparison of radionuclide liver scan findings with hepatic biopsies gave similar results. During therapy, 65 follow-up CT scans were obtained in 46 patients. Scan abnormalities improved or disappeared in 11/12 cases with tumor response documented in other ways, appeared or worsened in 5/13 cases of tumor progression that was diagnosed by other tests, and only rarely (2/65 scans) improved at the time of documented tumor progression, or vice versa. In only three patients, however, did CT scan provide the sole site of evaluable disease during treatment or detect either the only area of residual disease in a patient in otherwise complete remission or the initial evidence of tumor progression. Although abdominal CT scans in SCC can demonstrate metastatic dissemination not evaluable by other means, they provide relatively little therapeutically relevant information beyond that obtained with standard staging procedures.

Contribution of angiography to the diagnosis, staging and assessment of radiation and chemotherapy of solid abdominal malignancies in children.

Sequential angiographic studies were done in six children to stage and assess the results of radiation and/or chemotherapy of solid abdominal malignancies: one bilateral Wilms' tumor, two neuroblastomas, two hepatoblastomas and one hepatocarcinoma. Angiography was of value in demonstrating the tumor, its location, extent and vascular characteristics, as well as its regression and recurrence. Wilms' tumor and neuroblastoma responded and well to radiation and chemotherapy with substantial decrease in tumor size and regression or disappearance of tumor neovasculature. Resceted tumors revealed this to be due to tumor necrosis, hemorrhage and/or cystic degeneration. Hepatoblastoma and hepatocarcinoma did not respond as well to chemotherapy, with only mild decrease in size and neovasculature of the tumor.
